Definitions
- the present invention relates to a compressed air or gas distributor placed or not at the end of a cylinder piston and which, after its activation, has a automatic operation caused by pressure and air depression in the cylinder.
- the present invention also relates to an achievement in kit form or integrated into everything mobile assembly driven by compressed air or pneumatic pressure (possibly pressurized gas other than air).
- compressed air by a means mechanical implemented by the operator at the time of charging (hand pumping), or a compressed gas, such as that the carbon dioxide in a cartridge is distributed from a storage chamber to the barrel of tear. This distribution is done by means of a valve actuated by pressing the trigger.
- US patent US-A-5,400 536 describes a rotary and double barrel pistol action, presenting a cylinder in line with the barrel for the projectile fire.
- a rod secured to the piston of the cylinder is struck by the dog, which opens the valve and releases pressurized gas into the barrel.
- U.S. Patent US-A-5,613,483 discloses assembling a piston and a cylinder for a handgun gas.
- the piston can move back and forth, between a loading position and a firing position.
- the cylinder has two chambers through which moves the piston.
- the piston When the piston is in the position of loading, the cylinder is in communication via the first chamber with a gas supply device under pressure. This position of the piston prevents any communication between the two rooms.
- the piston rod is provided with a passage section at the contact with the cylinder which extends from longitudinally.
- document US-A-5,363,834 describes a weapon having a first operating mode for the propulsion of a projectile by compressed gas contained in a cartridge and a second operating mode for compressed air propulsion generated by a manual pumping.
- the aim is to be able to remedy a failure of the compressed gas supply system (dioxide of carbon).
- a manual switch operable by the shooter allows switching from one operating mode to another, by bringing a storage chamber into contact with either the gas compressed, or with the compressed air obtained by pumping. then from the shot, the dog strikes a cylinder piston element which releases pressurized air or gas to the barrel tear.
- the present invention aims to provide a jack and its compressed gas distributor, preferably in line, fully automatic after activation by an initial impulse.
- the invention has the complementary aim of ability to provide, for certain applications, such a cylinder and its distributor in kit form, easily adaptable on existing equipment.
- the invention also aims to provide such a distributor which is compact, that is to say causing a very small increase in the length of the cylinder by distributor integration, simple and easy to production.
- the invention aims to propose a pneumatic automatic distributor usable in a large number of technical fields and not limited to specific armaments sector.
- the present invention relates to a automatic device for the distribution of compressed gas, for example air or compressed carbon dioxide, comprising a cylinder constituted a cylinder in which can slide a piston provided a piston head, said cylinder being provided with a closable front end, called distributor support, a distributor located in the extension of said cylinder.
- the dispenser can be ordered directly by the front of the piston.
- the distributor has a gas supply compressed, a chamber that can contain said gas under pressure being dynamically located between the end lockable cylinder and piston head.
- the device comprises a valve capable of open and close along the cylinder axis and a seal double allowing the opening and closing of the arrival of compressed gas, the valve being provided with a spring reminder such that at equilibrium, it is detached from the joint double, rear side, the double seal being provided with a return spring such that at equilibrium, it closes the arrival compressed gas.
- the piston head can come into contact at the front of the cylinder with the valve, this which causes the integral recoil of said valve and the double seal with stop against the distributor support, this which causes admission by a compressed gas supply in the bedroom.
- pressurized gas escapes either through outlet of the piston out of the cylinder, either through a fitted orifice in the cylinder, the piston then remaining inside the cylinder.
- the piston is provided with a return spring which tends to bring it back towards its equilibrium position at the front of the cylinder.
- the bedroom not being or being weakly pressurized and the piston no longer in contact with the valve, the valve and the double seal are in their equilibrium position under the effect of their respective return springs and the valve is detached from the double seal, allowing a exhaust of gas contained in the chamber through a orifice provided in the wall of the distributor support, the double seal being in the closed position of the arrival of gas under pressure.
- the contact between the piston and the valve is produced by means of a control striker capable of slide freely inside the piston, the part rear of the striker having been struck initially by the hammer.
- the dispenser can be controlled by a traction device placed in front the assembly constituted by the distributor and its cylinder.
- the traction device replaces the percussion initial piston with a hammer.
- Another advantage is that ability to easily reset activation element (hammer) of the distributor by the recoil of the piston.
- the cylinder / distributor device of the present invention is advantageously usable with pistol-type weapons (with slide) or rifle (with movable breech).
- Figure 1 shows an exploded view with nomenclature according to the principle of control by a striker passing through the piston of the jack according to the invention.
- Figure 2 shows a sectional view longitudinal of the different parts of the cylinder / distributor of Figure 1, as well as a detailed view, in the position of rest, with the compressed air supply blocked.
- Figure 3 shows a sectional view longitudinal of the different parts of the cylinder / distributor of Figure 1, as well as a detailed view, in position activation of the distributor for air opening.
- Figure 4 shows a sectional view longitudinal of the different parts of the cylinder / distributor of Figure 1, as well as a detailed view, in position recoil of the piston, with the compressed air supply open.
- Figure 5 shows a sectional view longitudinal of the different parts of the cylinder / distributor of Figure 1, as well as a detailed view, in position piston outside the cylinder tube, the compressed air supply being closed.
- Figure 6 shows a sectional view longitudinal of the different cylinder / distributor parts Figure 1, and a detailed view, in the return position the piston of the cylinder moved by its spring with exhaust from compressed air through the distributor.
- the air distribution device automatic tablet according to the invention can be produced in kit form or integrated into any mechanism such as rifle or pistol especially for shooting simulation or in any mechanism depending on the possibilities exploitation of the advantages of the invention.
- activation initial of the dispenser is obtained by percussion of a striker 9 which can slide freely inside a piston 80, by means of a hammer (or hammer) 15 which can be an original part of a weapon or equipped device automatic compressed air distributor according to the invention.
- Percussion is by pivoting towards the front of the hammer 15 in a recess of the piston body 8.
- FIG. 3 shows the position opening the air supply.
- a striker 9 which passes through the piston 80 of the jack and is controlled by a hammer 15 which strikes said striker 9.
- the latter transmits its linear movement at valve 5 of the distributor.
- the valve 5 then comes into contact with the seal of distributor 3, the latter moving to the left, this which allows compressed air to pass between the assembly attached seal 3 - valve 5 and piston head 11 of cylinder.
- Figure 5 shows the position of depressurization in the cylinder.
- the piston 80 recedes cylinder the latter can either exit the cylinder tube or cylinder 1, or stay in the cylinder thanks to a lateral air exhaust 12 located in the cylinder tube 1. In both cases, this has the effect of causing the pressure in the cylinder tube 1 and, at the same time, decrease the pressure on the distributor seal assembly 3 and valve 5.
- the assembly 3.5 can then, under the effect of respective springs 4.6 of the two parts 3.5 resume its initial position to the right (figure 6), which closes compressed air supply thanks to the double circular joint distributor 3. This also allows the escape of air still in room 10 when returning piston 80 of the cylinder which, moved by its spring (not shown) returns to its initial rest position towards the left.
- the air exhaust is achieved by detaching the valve 5 from the seal distributor 3, through the lower hole 20 of the support of the distributor 2 (see detail view of FIG. 6).
- the compressed air supply remains blocked at this stage and the system returned to its original rest position. The complete sequence of cylinder and distributor is therefore carried out automatically since it is initiated only by the impulse of the hammer 15, without that any other intervention is necessary.
- the striker part 9 could be absent and be replaced by direct contact between the piston 80 of the jack and the valve 5, which would have effect when closing the cylinder to the left, would automatically have all the functions available illustrated in Figures 3 to 6. To stop, in this configuration, the operating cycle, just to interrupt the piston of the cylinder tube before its contact with valve 5.
- the device of the invention can be produced as a kit to be mounted directly in fire simulation weapons or be adaptable to any other mechanism, either as a kit, or integrated into a more complex, whether or not requiring modifications to the system original.
